To all whom, 25j may concern/:

Be it known that I, TI-IOMASMIDGLEY, a

`citizen of the United States, residing in the. city of Hartford, county, ofV Hs'irtford,and' State of C'OnnecticutLhave invented' new and useful Improvements, in VY/'heel -Rims,` of whichthe 'following' is 'a specification.

l This invention relatcsfto;Wheel-rims, :and

more particularly toa-fclip'y or cover for the4 joint in a contractib,le.and.-expansible y'side flange for suchri'ms'.'

I 4' 1 t cannot become detached therefrom, but

-canbeswung out of the way-to permit access I The object; of the invention istojprovidefa jczlip .or coverfor,` `the joint al contractible andexpansible side flange 'which is securely fastened to .the side flange in such a way that to the joint and can `he conveniently fastened in position to. cover the joint completely and 'protect a resilient wheel.- tire from injury through contact with the edges presented byl the ends of the side flange at the joint.

A. further object of the invention is to providel a contractible and expansible side;

flangiel with a clip or cover for the jointthere- 'chserves not only to protect a resilient inw tire from'injury'through contact with the -ends of the side flange, but also assists in securing the side flange upon the seat-provided therefor upon the wheel-rim.

With the objects above stated in view,

as Well as others, which will hereinafter appear, the invention consists` in certain features of construction, arrangement, andv combination of parts hereinafter described, illustrated in the accompanying,l drawings, and particularly pointed out in the appended claims. I

In the drawings, Figure l is a perspective view of the joint in a contractible and eX- pansible side flange, together with the adjationwiththeclip'to serve as a flange-securing-device'. l l A-'s is well known, `manywheel-runs characterized-byremovable side ilangeshave been devised for the reception of elastic tires, the

side, flangesfbeing made removable to facili- Vtate the' application of the tires to the rims andthe removal of the tires therefrom. Many'of the removable side lflanges devised are provided with .means for .expanding and contracting them, and in such side flanges a turnbuckle or equivalent deyiceisordinarily employed, the turnbuckleibeing placed between the ends of the side flange in substantially the manner indicated in l. In side flanges ofl this type the edges or shoulders presented by theends of the side flange. lwillsoon injure a pneumatic tire to considera-ble extent if no protecting clip or cover is provided. to iprevent contact of the tire 'with these-edges or shoulders.4 Protecting clips or covers for these side flanges may be position, and there 'is but little dangerof such clips or covers becoming detached as longas the ltire 'remains inflated. When,

however, the tire becomes deflated, the clip.

is apt to become .detached from the side flange, and so make injury to the tire inevitable. The clip which forms the present invention is so constructed that its accidental removal is impossible, and it also supplements the action of the turnbuckle in securing the side flange upon its seat, thus relieving the turnbuckle of a portion of the strairnto which it is subjected.

Referring to the drawings, in which corresponding parts are designated by similar characters of reference inthe several views, l designates the side flange proper, which engages a seat on the wheel-rim A. The turnbuckle 2, which connects th ends of the side flange, mav of any ordinary or preferred type, but is preferably partially inclosed by the ends of the side flange. The clip 3 lits closely over the side ange andis provided TOO with arms 4 and 5, extending therefrom at the ends, and is secured to the side flange adjacent to the joint by means of a screit7 @which v extends through a suitableopening in the arm 4 and serves as a pivot about Which the entire clip turns. The arm 5 is longitudinally slotted at 7 for the r ception "of a .securing-screwr 8, and the outer surface of the rim 5, adjacent to the slot 7, is transversely serrated, as shown at 9. These serrations are provided to cooperate With the serrated face 10 of a locking-plate 11, which is secured in 'greater thickness and strength than is lrequired for the portion of the cli which serves as a cover or shield for the joint in the sidel The use of the clip above describedfwillbe understood from the descri tionand the accompanying drawings. raised, as shown in Fig.. 1- free access tothe turnbuckle 2 is permitted, so that the side llange may be expanded or contracted at Will.

After the sideflange has been secured in'position upon the seat provided forit on the wheel-rim the clip is depressedy into the position shown in Fig. 2, and the fastening-screw 8, 'with the locking-plate 11 mounted thereon, is introduced' into the 'threaded 'holev14, provided for it in the side flange. When the screw 8 is tightened, the locking-plate 11 will be brought into positiv/e engagement with the serrations provided on the arm 5 of the clip, and the bar 13 will then form a supplel mental securing device to assist the turnbuckle in withstanding the strain imposed upon the side flange When the tire is inflated. As long as the screw 8 is in position the arched cover 12 will be kept in position over the turnbuckle and the adjacent ends of the side flange, and any injury to the tire from contact With the ends ofthe side-flange or lturnbuckle will be impossible. To permit access to the turnbuckle for removing the 'side flange, the screw' 8 and the locking-plate 11 are removed,and the clip may then be raised into position shown in Fig. 1', thus exposing the turnbuckle so that it may be readilyoperated.

'hen the clip lis said joint pivoted at one end -upon the side flange and provided at the other end With means for positively fastening the clip in position. i

4. In a wheel-rim, the "combination with a' side flange having'a joint therein, of a 'clip' or cover for the joint comprising anar'ched portion extending over the joint and oppositelyextending arms having openings for the reception of fastening devices.l

5. In a Wheel-rim, the combination with a' side flange having a`joint therein, ofv contracting and expanding means disposed'in saidl joint, and a clip or cover for saidjoint, said clip or cover being prqvided With means for positively securing it inposition.

6. In a wheel-rim, a side flange' transversely divided at one point, and a pivoted clip or cover positively attached to said side flange, adjacentv to one end and provided at the other end With means for fastening Vit to the other end ofthe side flange. 7 In a Wheel-rim, a side flange having a joint therein, a clip or cover for'said joint having a portion. of its outer surface serrated, alocking-plate having a serrated face for engagement vWith the serrated portion of the surface of the clip or cover, and means for forcing the locking-plate -int'o engagement with the clip or cover. A

8. In a Wheel-rim, a side flange having a joint therein, alclip or cover pivoted at one end to said side flange adjacentytov the joint and having at the other end a longitudinal slotted arm, said arm being serrated on its outer surface, a locking-plate having a serrated'face `adapted to cooperate With the serrations on said arm, and a screw extending through said locking-plate and through the slot'in said arin.

In testimony whereof I aflix my signature in presence of tWo Witnesses.
